Some hair node group suggestions

Hello,

Creating a parting with the interpolate node needs the geometry to be cut to separate islands. I personally find this a bit "destructive", so I adjusted the node group to work with a texture map. Could something like this maybe be an additional default option ?

Also, the "create guide index map" group has a guides input. However the node is not actually using those guides as output, but takes existing curves which are closest to the input guides as actual guides. A use case would be to delete i.e. 90% of the current groom, deform those 10% slightly with some noise and use them as new guides for sub-clumping. The noise is optional, but helps to break up perfectly parallel sub-clumps.

Luckily we're having this amazing flexibility to alter the node groups to our liking, those two proposals can be implemented by anybody themselves. Some users (including me) however are quite intimidated by the underlying setup of these node groups.

Thank you very much, Stefan
